OIL nisrnnsna.

Application. filed April 3, 1925.

This invention relates to liquid dispensers, and especially to an improved oil dispenser.

At automobile supply stations, a considerable amount of time is consumed in putting oil in the crank cases of automobiles, especially in cold weather, when the oil Ais comparatively thick and sluggish. Besides, there is a considerable loss to the consumer because of the quantity-of oil which remains on the internal surface of the measuring vessel, where the force of gravity alone is depended on for forcing the oil from the measuring vessel. Therefore, one object of this invention is to provide a measuring and dispensing vessel in combination with and in communication with a compressed air receptacle or container, and to provide the latter with an air inlet valve which is quickly and easily connectible with a pump such as is ordinarily used for inflating pneumatic tires, so that this device may be operated by the equipment at hand at most every automobile supplying station.

Another object is to provide a dispensing device of this cl'iaracter, the oil container of which is transparent, so the consumer or purchaser can be .sure that he is receiving the proper measure of oil.

Another object is to provide a device of this character which, while being comparatively light, is of the proper shape to sustain the heavy air pressure without danger of bursting or distorting the device.

Another object is to provide a device of this character which is composed of sections having air-tight connections, such sections being separable from-one another for the purpose of gaining access to the valves and their adjuncts, also to permit replacement of any glass member Wllh may become broken.,V

Another object is to provide a device of this character having a valve-centrolling handle protected within the arched or concavo-conveX bottom, but is in readily accessible and convenient position for manipulation when the device is being used for dispensing the oil into the crank case of a motor vehicle. Y i

Other objects and important features are pointed o ut or implied in the fol-lowingdetails of description, in connection with the ligure of thel drawings which is a view partly inside elevation and partly incentrati-vertical section and ,illustrates the preferred construction embodying the inventive ideas.

In these drawings, a sheet metal air-tank includes a cylindrical wall 1, a concaveconvex bottom 2 and a concavo-convek top part 3, these three elements being secured together in air-tight relation, and because of the. curvature of each of these elements, they 'ferm an especially rigid or unyielding resistance against any distortion by theforce of compressed air therein. Any ordinary form of air valve -l may be provided at any convenient place through the wall 1, and be used in connection with any ordinary tirepump for con'ipressing in 'this air-tank.`

A marginal gasket seat 5 is formed on the upper face of the air-tank and forms part of the top of the latter, a gasket 6 is seated thereon, and a hollow glass member 7 has its lower annular edge seated on this gasket. This memberl ".7 is molded with sere w-threads (f5 which mesh with screw-threads 9 formed in an annular upstanding flange 10 which is preferably an extension of the gasket .seat 5 and of the wall 1. By screwing the 4member 7 idown tight on thegasket 6, a liquidtight joint is provided between the air-tank and the glass member 7. This glass member combines with the Harige or annulus 10 and with the top part 3 of the air-tank, thus forming the oil container which may receive the; oil through itsexternally threaded tubular mouth 11. A metal cap 12 is screwthreaded on the externally threadedv mouth 11, and a spout or tube 13 extends through this cap and provides an outlet through which the oil is dispensed into the crankvcascs of the motor vehicles.A This outlet tubev 13 is shown broken off, it being understood that such tube may be ofany appropriate length, also of any appropriate` cross section, and it may be provided witha cap or other appropriate stopper forpreventing dust and other foreign matter fromy getting into the oil. A gasket 14;` is provided between the glass member 7 and cap 12.

A simple and very eifec-tive form of valve mechanism is here shown for controlling the iiow of air from the air chamber (indicated at15)Y intol the oil chamber (indicated at 16), such valvemechanism including an outer tubular member 17 and an inner tubular member 18,the latter having its lower end closely fitted`r in the upper end .of the member 17.

'Til

This memberlS is provided with a valve seat .19 into which. extends` a conical endkof a valve needleZO, the latter being threaded vat 21 inte the lower end o'fthe member 17.

llc

This latter member is provided with an inlet 22, so that compressed air can pass from the chamber 15, through the member 17, thence through the member 18, and thence into the oil chamber 15, that is, when the valve is open; but when the valve is closed, air cannot pass from the chamber 15 to the chamber 16. rThe needle 2O may be provided with any appropriate form of handle 23, and this handle is located within the hollow of the arched bottom 2, out of the way, and out of danger of being accidentally turned.

In constructing a device of this character. the tank-wall 1 is preferably formed of seamless tubing, and is spun, pressed or otherwise formed to include the gasket seat 5 and the threaded annulus 10. The parts 2 and 3 may be spun or pressed from sheet metal, centrally apertured, and formed with appropriate margins for securing them to the lowe er end of the wall 1 and to the gasket seat 6 respectively. For securing the arched bottom 2 in place, the wall 1 may be turned inward and upward around the margin of this part 2, and these parts 1 and 2 may be soldered at 24 and 25, thereby not only rendering this part air-tight, but also providing maximum strength against the pressure of air therein. The top part 3 has integrally formed therewith a plane marginal part which is soldered at 26 and 27 and thereby united with the gasket seat to form the top or cover of the air chamber. After the air chamber is thus formed, the member 17 is inserted through the central opening of the member 2, the member 18 is inserted through the central opening of the top part 3, and forced into the member 17, and then the latter is soldered at 28, and the member 18 is soldered at 29. The solder not only adheres to the peripheries of the flanges on these members 17 and 18, but also flows into the joints under these flanges, or between them and the parts 2 and 3, thereby making these connections air-tight and very stron.

Any suitable form of handle (not shown) may be secured to either the wall l, the concaved or arched bottom 2 or both, or may be molded integrally with the glass member 7.

1n preparing this device for dispensing oil into the crank case of an engine, the cap 12 is removed, the chamber 16 is filled with oil through the mouth 11, the cap is replaced, and the air is now forced into the chamber 15 through the valve 1, the valve-member 20 being seated in the valve-seat 19, so no air can now pass to the chamber 16. The desired air-pressure is thus obtained and maintained in the air-chamber.

1n dispensing the oil into the crank-case, the device is inverted, and its spout is placed in the inlet of the crank case, then the valve 19-20 is opened, and air passes from the chamber 15 to the chamber 16 and exerts a pressure on the oil, thus hastening the ow of oil from the oil chamber into the crankcase. 1t is to be understood that the oilchamber is of a standard measuring capacity, or may be made of different capacities, as one-quart, one-half-gallon, etc. and, being transparent, the purchaser can readily see thlat he is receiving the desired quantity of o1 It is Within the scope of this invention to place any ordinary form of check-valve (not shown) in the air-passage between the chainbers 16 and 15, or to make the valve lil-2u spring-pressed, so oil cannot flow into the air-chamber in the event the user fails to close such valve.

I do not intend to limit my patent protection to the enact construction, arrangement, dimensions or materials here shown and described, but the inventive ideas include numerous changes and additions which may be made without departing from the spirit and scope of the invention.
